To a/ZZ whom i ma/y concern'.

Be it known that I, FREDERIC G.. Nico- LAUs, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga .andState of Ohio, have invented certain new and useful Improvements in Registers and ventilators; and I hereby declare the following to be a full, clear, and exact descri tion of the invention, such. as will xo enable ot ers .skilled in the art to which it pertains to make anduse the same.

This invention relates'to improvements in registers or ventilators.

One object of this invention is to improveV i 5' the construction of the slatbearing frame of z 5 |slats during their operation.

Another object is to construct the slatbearingframe, the slats, and Slat-operating mechanism in the main of sheet-metal parts and to provide the sheet-metal frame with a 3o suitably-attached castmetal face-plate.

` With these objects in view and to the end of realizing other advantages hereinafter appearing this invention consists in certain features of construction and combinations of parts hereinafter described, andpointed out 4o ofthe device in their open position.

' in the claims.

.In the accompanying drawings, Figure 1 is a front view of a register or ventilator embodying my invention with the rotaryFslats 1g. 2 is a section on line 2 2, Fig. 1, looking in the direction indicated by the arrow. Fig. 3 is a section on line 3 3, Fig. 2, looking in the direction indicated by the arrow. Fig. 4 is a rear .1.5 or inner side view of the register or ventilator,

5o' that in Fig. 6 the slats are shown in with the face-plate removed. Fig. 5 is a section on line 5 5, Fi 1, looking in the direction indicated by t e arrow. Fig. 6 is a section corresponding Withv Fig. 2, except their closed position. Fig. 7 is an enlarged view of a portion of Fig. 3 and is illustrativel of the Slat-o erating mechanism. Fig. 8 yis 'an-en- -large Ahorizontal section in detail and online 8 8, Fig. 2, illustratin the operative connection'between one of t e rotary'slats andthe sl at-operating bar. Fi 9 is 'a section online 9 9, Fig. 6, looking in the direction indicated by the arrow. j

Referring to the drawings, A indicates the perforated orapertured cast-metal face late of the register orA ventilator. The said' aceo eningsA for accommodating the passa e' ci) airl therethrough. quadran lar in p an Aand exten s over thev outer si e of the space surrounded by the The face-'late A is.

'plate is' provided in the usual manner with slat-bearingframe, which is provided withl rotary arallel slats B and consists in the main o sheet-metal channel-bars D Aand E. Aslat-bearing frame made of sheet-metal arts possesses greater strength and durabilityl than a frame which is composed in the main of cast-metal parts yand a cast-metal face-plate, not bein yieldable as a stamped steelv or sheet-metal ace-plate, is not liable to have its japanned surfaces cracked or injured when ste ped upon or knocked against, whereas t e inward yielding of a stamped steel or 'sheet-metal face-plate will invariably in the course of a short time result in the crackingI or mutilation ofthe japanned surfaces of the face-plate. Each slat B is pro-` vided centrally of each end thereof with a trunnion b, with the trunnions of both ends of the slats arranged in line endwise. The

space in which the slats B are, adapted to operate is surrounded by the quadrangular Slat-bearing frame of my improved register orv ventilator, which frame comprises tWo sheet-metal channel-bars D, arranged at opposite ends, respectively, of and supporting the slats. The bars D are arranged at or a proximately at a right angle to the slats T lie Slat-bearing frame also comprises two other sheet-metal channel-bars E, which are arranged at opposite ends, respectively, of the slat-su porting bars D and parallel or approximate y parallel With the slats.

The Slat-bearing frame isreinforced at the.

corners and interiorly by angle-plates G that is, an angle-plate G is arranged at each interior corner formed between the adjacent ends of adjacent bars of the Slat-bearing IOO frame with one of the wings of the said angle# plate riveted, as at G', to one of the said bars and with the other wing-of ythe said angleplate riveted, as at-G?, to the other of the g, which has ascrew-threaded holeg, (see` Fig.` 5,) and the face-.plate A is provided in u registry with the said hole g with a hole a,

-. removably secured to -Which is-countersunk toreceive the head of a screw .,j Thescrews Y f extend through the face-p ate and engage` the correspondinglythreaded holes g formed in the ears g of. the angle-plates G. The face-plate istherefore cach angle-plate G at i the outer end of the angle-plate.

'- jecting flanges d and dgarranged at the outer provided at its inand inwardly pro- Eacl'channel-bar D is ner'side withtwo laterally side andinner side, respectively, of thespace surrounded by the Slat-bearing frame, which i flanges extend longitudinally of. the bar'. 25

Each channel-bar E side with two laterally and inwardly `projecting flanges e and e", arranged at the outer side is provided at its inner and inner side, respectively, of the space surrounded by the Slat-bearing` frame and extending longitudinally of the bar.

The flanges d and e of the bars D and E, respectively, are arranged next adjacentto the inner side of the face-plateA, which con-l sequently abuts against the outer sides ofthe said flanges. f

Each angle-plate G extends from the outer flanges d and e to the inner flanges d and e of the` adiacent bars D and E, respectively, being arranged between the outer and inner flanges of each of the said bars", and the ear formed upon the said angle-plate is arranged next adjacent to and overlapped atits outer side by the said outer flangesd and c, which consequently extend over the outer side of the said carand are snugly interposed be' tween the said ear and the face-plate A. The

the bars l) and E obtherefore, afl'ord bearing to the inner' outer flanges d and c of v1ously,

side of the face-plate and also afl'ord bearing to the outer sides of the ears of the angle# plates. j

The -inner flanges d of the-slat-supporting barsD project first laterally and inwardly .longitudinally ofi-the said flange.

the inner side of I connection, between` each slat and then outwardly, as at d2, in the direction of the outer side of the space surrounded `by 'i the slat-bearing frame, with the outwardlyroiecting portions d2 .of the said flanges af'fff ording bearing to the trunnions b of the slats B, and :the last-mentioned and trunnion-bearing portions of `the flanges d of both Slat-supporting bars D possess enough springiness to render them capable of yieldy ing laterally independently of the remaining l portions of the said bars. by pressure exerted i against the inner sides of the said flanges, so as to accommodate the springing of the slatl bearing bars into position between the said trunnionfbearing portions of the said flanges during the assemblage of .the parts, and thereby bring the said trunnions into engagement with the circular trunnion-receiving holes d3 formed in the said yielding members d2, which are arranged at a right angle to the trunnions. `Obviously a slat can be readily removed, rif necessary forany reason, b spreading apart the yielding portion d2 of the flanges d of the Slat-supporting bars by pressure exerted againstthe opposing sides of the said flanges. lt will be observed that the surrounding wall of each hole d surrounds the engaging trunnions b, as shown in Fig. 9, and that the portionsd2 ofthe bars D' prevent displacement of the trunnions outwardly toward the face-plate.

' I would here remark that the thickness of the sheet-metal parts of my improved register ori ventilator is shown exaggerated inthe drawings.

AThe inner flanges e ofthe bars E (see Fig. 6) form stops arranged to limit the turning of the slats in actuating them from their open into their closed position:

A sheet-metal` Slat-actuating bar. K is arranged between' the trunnion-bearing portion d2 of the flange d of one of the Slat-supporting bars D a'nd the face-plate AV and extends The slatactuatingbar K is consequently' arranged at and` extends longitudinally of the adjacent Slat-supporting bar D and extends across the outer sides of the arms B', formed upon the adjacent `ends of the slats B. `The arms B ofallthe slatsB are arranged in line edgewise and project laterally in the same direction, and theslat-actuating bar K `is provided with a laterally and inwardly projecting flange 7c, which extends longitu dinally of the bar and is arranged to overla i the adjacent edges of the slat-arms, whicil flange materially stifiens and reinforces the said bar and forms a guard, afl'o'rding profeetion to the said arms.

The slats Bare pivotally or operatively connected to the Slat-actuating bar K, as already indicated, and the pivotal or operative and the said bar '(see Figs. 4, 6, and 8) Acomprises a pin L, which extends through the slat-'aetuating bar and loosely through the arm B of the said slat and is provided between the said arm and bar with an annular shoulder' or diametrical enlargement l, which pin is upset,

vI2C) as at L', af the outer side of the slat-ar-,tiiating bar. The pins L, establishing operathf'e connection between the slats and the slataetuating bar, are of course parallel with the trunnions or axes of the said bars.

A sheetmetal oscillatoryi segment R, in-

' imlty to the flange d of the said bar, with of the said segment.

` pin P has a head p overlapping the inner side ing bar D.

tains the segment in the pivotal connection between the said segmentand the said bar D formed by'a pin l', which is arranged parallel with the slattrunnions b and extends loosely through the segment and through the said bar D. The

of the segment R, which pin is upset, as at. P at the outer side of the segment-support- A spring S is mounted and confined upon the pin P between thesegment and the adjacent or inner side of the segment-supporting Slat-bearing bar D. The spring Smainfrictional /contact with the head p of the pin P, and consequently there is enough frictional engagement etween the head of the segment and the said pin to deter the segment from' accidentally turning on the said pin.v The spring S consists, preferably, of a sheet -metal piece arched or bowed .centrally between its endsA and having both end portions converging toward their free extremities and loosely mbracing the pin P, so as to cause the said sheet-metal piece not only to operate as a spring, but to be positively retained in place between the segment R and the segmentsupporting Slat-bearing bar D. Thel segment R is offset inwardly above the pin P, and the inwardly-offset `or u per portion of the segment extends u ward y into an a erture or opening A2, wit which the face-p ate A is provided to accommodate the operation The segment R is provided Within the opening A2 (see Fig. 7) with a laterally and outwardly projecting flange r, which is arranged concentrically of the axis of the segment,which flange is corru-` gated transversely to render it capable of being readily operated by the application ofthe foot of the operator.

The segment R is operatively connected with the Slat-operating bar K, and the operative connection between the said bar and the said segment preferably comprises a pin l which loosely engages a slot R', formed centrally in and arranged radially of the inwardly-offset portion of the segment. he pin T extends through the Slat-actu ating bar K and is provided between the said bar and the segment with an annular shoulder or dia- 1 metrical enlargement t, and the inwardly-offset portion of the segment is preferably indented inwardly, as at R2, around the pin T, to accommodate the reception of the saidV shoulder or enlargement of the said pin almost or approximatelyflush` with the inner surface of the inwardly-offset portion ofthe segment. The pin T is upset at its inner end, as at T, at the inner side of the Slat-actuating bar K. l

t By the construction hereinbeforedescrbed `it will be observedthat there is no liability of the Slat-actuating bar' becoming disconnected from the arms B" of the slats, nor is there any liability of the segment R becom- 'I ing disconnected from the Slat-actuating bar.

The constructionk is simple, strong, andY durable, and the number of parts required to.'

support Vand retain the slats is reduced to a i" minlmum.
